How this service works
New releases of tracked Rust crate packages (serde, tokio, clap, reqwest, and more) on crates.io (Rust) since a timestamp — each tagged new_release or breaking_change (major-version bump) with a 1-10 significance score. Answers "did a dependency in my Cargo.toml ship a new or breaking version I should pin or upgrade?" Pass ?package=<name> for ANY Rust crate package on demand.
Output
A JSON object with a count, a source label, and an array of change events — each including the change type (new_release or breaking_change), entity ID, summary, significance score (1-10), detected timestamp, effective date, and a source URL linking to crates.io or the changelog for verification.
Example use cases
Example prompt
“Show me any new releases or breaking changes for the tokio crate since 2025-01-01T00:00:00Z, with a minimum significance score of 6.”
Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/crates/changesWhen to prefer
Use this endpoint when you need programmatic, scored change detection for specific Rust crates — especially for dependency monitoring, automated changelog alerts, or CI/CD pipelines that need to react to breaking changes. Prefer it over manually scraping crates.io when you want significance scoring, filtering by severity, or on-demand tracking of any crate not previously registered.
Side effects
- Unknown or misspelled crate name returns empty changes array or 404
- Invalid ISO-8601 timestamp in 'since' causes 400 validation error
- Package exists on crates.io but has no new releases since the given timestamp — returns empty array with count 0
- min_significance filter too high (e.g. 10) may return zero results even when changes exist
- Service unavailable or upstream crates.io API unreachable returns 5xx error
- Payment not processed (x402 protocol) results in 402 Payment Required before data is returned
